Coefficient of determination (r 2) and Bland–Altman plot. Top panel Correlation between blood glucose measured by the OptiScanner® (Y axis) and that measured using the YSI blood gas analyzer (X axis) with a statistically significant p value. Lower panel Bias and limits of agreement between blood glucose measured by the OptiScanner® (OS) and by the YSI (Bland–Altman method). LLA lower limit of agreement, ULA upper limit of agreement
